Multijet production in neutral current deep inelastic scattering at HERA and determination of alpha_s

Articolo
Data di Pubblicazione:
2005
Abstract:
Multijet production rates in neutral current deep inelastic scattering have been measured in the range of exchanged boson virtualities 10 < Q2 < 5000 GeV2 . The data were taken at the ep collider HERA with centre-of-mass energy sqrt(s) = 318 GeV2 using the ZEUS detector and correspond to an integrated luminosity of 82.1 pb-1 . Jets were identified in the Breit frame using the kT cluster algorithm in the longitudinally invariant inclusive mode. Measurements of differential dijet and trijet cross sections are presented as functions of jet transverse energy, pseudorapidity and Q2. Next-to-leading-order QCD calculations describe the data well. The value of the strong coupling constant alpha_s, determined from the ratio of the trijet to dijet cross sections.
